o This invention' has'todo shliggtools f l y of the variety designed and adapted for pieking up objects that are more or less tubular` or oylindric inA shape, ysuch Y as pipe, dr1ll pipe,

- drill stems, drilling tools/,etcg and a general f object of' the invention is toprovide an efyfectiveishingftooll ofa simple character which may be easily appliedjtothe fish, which ,willeffectively take hold,' and `which mayv be y 10. easily releasedfro'm'its hold incasey 1t is found yundesirable kor Virnpracticable"to pull i vthe iish.'

f In satisfying'these v.objectsthe.invention takes the form of a sli carrier inwhich a set v 0f slip `or wedge mem rs,y preferably 1n the form Vof balls,operate-in.suoh ,fashion as to,

n .Y The whole mechanism is exceptionally simple, but is capableof specific design-1n a i varietyof forms, yas will bewell understood i Vby those skilledin the art.`after.read1ng the following ydetailed specification which 'de- 30 v'scribes a -specioand lillustrativey form of the device.: In connection withisuch description c reference vis had to thenccompanying draw- {in gsiliwhichv gf I f'f y f..

`This pipe ,or ftubing l-lfe'xtends: to the .top ,of the wellv andis theg'meansormfember `through 15 ,which the' lishing tool is operated@ The carrier member'k 10 has an interior tapering or conical bore 12 of suitable size and suitable taper angle. fr Within this bore I Vplace aL plurality of slip or vwedge members, herevshown'as comprising a plurality of balls; 13.7 Although any desired number of said' balls may be used, I prefer to utilize such a number as will substantially or nearly lill the rvcircle occupied by the balls when they are Ain their lowerlnost/and contracted position such as shown in Figurel. To prevent the -balls droppingoutof the carrier I preferably mount the balls Aloosely in a cage 14.

Any suitable kind of ball cage maybe used, itv only being necessarythat Athe cage hold thelballs loosely and allow. acertain latitude of radial movement to and `from the vertical central axis of the whole device. Such ball Vcagesare `well known and will need no particulardescription. f l Below the tapered conicalfbore 12 the carrier 10 vis'provided with aserew-threaded socket orbox 15 adaptedto take the screwthreadedpin 16 of the combined anchor and wedge lifter 20 about to be described. This v combinedy anchor and wedgelifter has at'its u per end aprojecting'annular` rib or flange ,1, adapted toenter the lower smaller'end' of the conical bore-12 andfto engagewith. and

lift theball cage and balls,as will be readily understood'froma comparison of Figure 1 and Figure 2. The screwthreads 15 are pref- ,erablysv right handed, so' that right handed rotation off the shing pipe 11V will screw `the carrier lOrelatively downwardly onto the? anchor member, or screw the anchor member relativelyupwardlyinto the carrier, to reach the relative .position shown inFigure 2.

The anchor member, designated by the nuy`meraly 2O,A has at'its lower end a plurality. of V.friction of drag springs 21 adapted resilientlyto engage the inside of the well casing C or, its equivalent, the wall of the'hole.l :These springsare of such formQand ,of such resilient `stiffness that .they .do notmaterially im- Io JOHN GEANnvoEl V20orgexatly,vertically `inthe Well.' v Frlnfhathsbeendescribedeit will bei f th Vpale-at;me'vtm-i115 of the' fishing tool up v and downin the well, but at the same time' @5er-idiot' the iish intotha't iternalirelellof the. j ball assembly.
